To all whom it may concern: 7

Be itknown'tha-t I, Fn DERIoK I-L Pnnnir, a citizen of the United States, residing at Beverly, in the county of Essex and 'State of Massachusetts, have invented certain new and useful Improvements in Insoles; and I do hereby declarethefollowing to be a full,

' clear,'and exact description ofthe invention,

such as Willenable others skilled in the art' same. p V Y V This invention relates primarily to insoles'for bootsand shoes and is especially {applicable to manufactured, i. e. lami nated or builtqip, insoles, although it is not towhich it 'appertains to make and use the limited in its application to insoles of that 111 making insoles forwelt shoes it has heretofore been customary .to provide a feather outside the fseiving-rilo which is of a uniform cross sectional thicknessand the surfaeeofvvhich lies in the same plane relav tive to the treadfface of the insole. Thesewing-rib and featherform together m n le into which the upper rnaterials are lasted. The thickness of the upper niaterialsis not uniform, there being a considerable {extra thickness at the toe portion caused by the insertion of the box-toe ,and additional' toe stifiening'. 7 materials; reason of this the welt, when seated upon the upper, the shoe being "then in inverted "position, rests 'in a higher plane relative :to the base of the toe portion of the insole than throughout the remainder of the shoe. Consequently considerable difiiculty is experienced tl1e operator of the-inseaihing ,n'iachine n seiving aroundthetoe. If the operator sews "high,

results and subsequently'v hen theoutsole attached the latter is held above lts proper plane at the toe and the correct line of the shoe is lost. If the sewing-rib is too low to permit the Welt to be sewed hlgh, the

operator will tip the shoesoasto sew o'full and thelong'stit'ch thus'fo'rined through the rib or between substance Will be exposed in the weltcrease of the completed shoe, pro; duciiig What is termeda grinnin inseam which further detracts from the appearance of thejs'hoe. The'diflieultie's' due to sue-h a raised position of the welt at the toe are even 'moreseri0us when ashoe, andespenal po tion' of a shoe and better fittedto overcomethe difficulties alooi'e outlined than insoles heretotore l cnown. 7

In accordancefwith this object, the invention, in' one aspect, consists in an v insole having its feather about the toe molded to lie in a different plane from'the-plane of the adjacent portionsjof the feather. In the illustratedinsole, the feather has a molded toe portion offset into aplane lower that the plane of the adjacent portions, that is to say, a lowe1" plane'when' the shoe is ininvertedposition forthe welt attaching operation, and as shown in; the accompanying drawings, but -Which "becomes a higher?

'ljh-ose skilled in the art will recognize that an insole having the characteristics defined will add'quajlity, accuracy andjperfeetion to shoe-making since its use overcomes all irregularity and lack of uniformity hereto: folre present in sewingthe upper to the inso e.

. A further object of the invention'is-to provide'agage on the insole by which tlieshoe may be placed 11 a definite predetermined relation to theop'erating instrumentalities of the machine which is to operate upon it. a In accordance with this ob ect, a featuieof th-ecinsole comprises a gage secured byproviding ,a forwardly facing abutment or shoulder at the end of the sewing-rib Where the 'inseaining operation is to commence. This will be at that en'd'of the rib which is on the outside-of aleftsoleand at that end of the rib which is on'the inside of right 'ele. "It is preferred that thegage be in the fornrof aniii-wardly turned end ontl'ie w rib thus forming a sliou'lderinside the rib into engagement with the channel guide of the inseamiiig machine before starting the machine and-whichwill not interfere with the usual feed of the shoe by themachine.

The present invention, in so'far as the feaj tures above described are concerned, is particularly applicable to manufactured insoles which aregen'erally pi'oducedffrom two or more layers of" sheet material, s nce in the process of their manufacturetne toe and the rib may readily befmolded to the ldesired shape.

In'manufactured insoles it is also desir- 7 leather substitute,fsuch as fiberboard of the same area, as the layer 8. ,"These layers'jto able to provide a" reinforce at the heel end of the insole to prevent the heel nails when the heel is inside nailed from drawing down pits orl'dep'ressions in the heel seat. a According-135 a st ll further object 'off the c inventionis so to fita manufactured insole formed from sheets of insole nrateriahthat a heel-seat reinforce may be inserted without destroying theblines of'the shoe or do ti'actiiig from its comfort to the wea 'eixf In accordance with this ohjectit is'coiiteniplated that a feature of the insole when manufactured of a laniinatcd structure'will comprise a transverse molding of the sheet material, forming the insole layers 'at about the breast line in a manner to raise the surface 'of tlie heel seatsuiliciently to permit layers while still. preserving a smooth socksurface The reinforce will be skivedat its v face'of the insole.

The inventioii' will "be described in'its ap- I plication to the manufactured we t insole illustrated in tlie di' awiii'gs although it is to back to 'ezrposejthe heel-seat rebeunid-erstood that certain featuresjof "the I invention are also applicable to others kinds of manufacturedinsolesor to" insoles formed froi'na blank of leather.'- Y y r e The type of ii'soleillustrated inthe drawings is alamina-ted insole for welt shoes'com- 1 posed of three layers of insolematerialr Al;

thoughno specific kind of material-is essential, it is preferred to use a textile fabric, such as duck, for one outside layer 5' forming the sewiiig siir'face,'-said layer being pro-- 'vided with amarginal sewing-rib 6,"which inay' bemolded therein at the desired flocation relative'to the edge of the insole, and a feather 7. The remaining layers form'the bo-dyr-layersfthe other outside layer '8' form;

ing a manufactured insole,

the ribbed face of the insole and also forms a corresponding offset in the ribbed face of the insole at the feather and around the toe. Consequently the last on which the insole is assembled must be providedwith a marginal .rabbet about the toe to receivetheofiset of the insole, as shown at 13 in .Fi the toe of the last is broken away. asjust described the portion 1 where In molding the feather offset produced is of StlfilClGRt. depth to co1n-- pensate for the extra upper m'aterials'at the toe, comprising the boX-toe,.its lining, the tip-or other pieces. The advantage accruing from fitting the insole in the manner just described will be apparent to those skilled in the art from aninspection of Figs. 3' and 4. Fig. 3 shows an IDSGEUlTSBWBCl high:

and the consequent distortion in the line of the welt creasedue to the abrupt rise at the tip line on to'the box feather of uniform and Fig. 4C shows the even line of the inseam obtained when the insole of the present invention is used, thus preserving the correct lineof the welt crease and providing an even surface on which to lay the outsole. A particular advantage of the present mode of fitting the toe of an insole to obtain the re sults just adverted to is that no part of the feather thickness is removed, thus'preserving in the shoe'the original uniform edge thickness and A further feature of the insole of the present invention as used for welt shoes resides in the formation of the sewing-rib at the end here the inseaming operation is. to coin-1 nience, with a gage 1 4 111 the form of a transverse shoulder the forward side ofwhich may be brought against" that side of the rhannel guide of the inseaming machine which faces in the direction'in which the shoe is fed during the inseaming. operation' The shoulder is so located longitudinally of the insole that when positioned as above described the inseam will be started at the correct point. as indicated above, withtberesuit that the shoulder will not interfere with the feeding of the shoe to the-left, as shown in Figs. 1 and 2. This, as will be'recognized by cial in'iportance. when to natic machinery. Preferably the gage l-l. is formed as a hook froindan inwardly turned portion of the sewing-rib and in maksuch as-has been described, it may be molded as a bead in the sewing-layer 5 at the same time that the rib is molded therein.

lVhile an insole having such a gage forms a part of the present invention, the method adjacent portions toe where an insole tlnekness 1s not molded,

consequently its entire those skilled in the art, is of espe-' making shoes on au-' having been indicated of'inaking shoes herein disclosed in which] suchan insole may be advantageously employed. for locating the insole and connected shoe parts relatively to an instruments for operating on the shoe, is not herein- It .is desirable 111 manufactured insoles of all types to reinforce t-he'heel-seat, since the strength of the materials used is not sufficient .toprevent theheel nailsif dri nn from the-inside from drawing down pits cr 7 depressions in the heel-seat. The reinforce is preferably.incorporated in such a way not to cause a protuberance at the heelseat which. would render the sock-surface of the insoleuncomfortable to the wearer of the shoe. As shown, therefore, the reinforce is inserted WitlHJI EII 'Oil SQt heel-seat formed the opposite side of the insole so as to retain.- the smooth sock-surface as shown in -l3ig. .1. The offset-:is pr'oducedby forming a transverse shoulder 15m about the breast line which may conveniently'bemolded in the insole material at the same time the shoulders 10 and 11' are molded therein. The-heel-seat reinforcelti is preferably inserted between the two body-layers prior to the molding operationand as a result the molding operation preserves the plane heelscat on the sock-surface layer because the:

space between the layers, formed by the molding of the-.shoulder 15;,gis completely filled by the reinforce. InFig. 5. the reinforce, because it is preferably made of relatively hard material, is shown as provided.

It is contemplate-l I on to the reinforce again. to cover thefheei I nails. 7 The reinforce is also shown as provid'ed, withcentral jig holes which,however,

do not form a part of the present invention, but are utilized inathe practice of'the method 0t i'nalung shoes forming the sub ectmiatter of the lVarren application Seriatno. (359, above referred to.

The reinforce 1s preferably skived at 1 forward edge as shown in Fig. 1 to fit as neatly as possible beneath the offset and to. avoid an abrupt rise on the feather where the welt. ends are butted and secured.
